Sealey FN12 Flange Nut Serrated M12 Zinc Pack Of 50

Designed for the most demanding fastening tasks, this pack of 50 M12 flange nuts from Sealey delivers exceptional holding strength and load distribution. The serrated flange face bites into the mating surface to resist loosening under vibration, making these nuts ideal for heavy-duty automotive, engineering, and construction applications. Manufactured from high-grade steel with a zinc coating, they offer reliable corrosion resistance for long-term performance.

- M12 thread size – the largest option in this range, built for maximum clamping force

- Serrated flange face provides anti-vibration locking without the need for a separate washer

- Zinc-plated finish gives good corrosion protection in workshop and outdoor environments

- Flange design spreads load evenly over a wider area, reducing surface damage

- Conforms to DIN 6923 standard for dimensional accuracy and strength

- Suitable for use with high-tensile bolts in structural and mechanical assemblies

- Pack of 50 offers excellent value for frequent or batch usage

Trust Sealey quality for secure, durable fastening in your toughest projects.
